How to verify only the elements names in a dictionary object?

Question

I have a VERY big dictionary in python and when I type dict.items(dic_name) it shows up so many stuff (matrix, vectors, etc). I just would like to see the elements names. What should I do?

For example when I have a list I type names (my.list) and it just displays the list elements name. Is there a command like that in Python?

好吧，如果你只有钥匙，请问钥匙，而不是物品：

my_dict.keys()

如果您严格要求它是一个列表，您可以这样做：

my_list = list(my_dict.keys())

现在，如果你想迭代它们：

在python 2中：

for k in my_dict.iterkeys():
    do_something_with(k)

在python 3中：

for k in my_dict.keys():
    do_something_with(k)
